If you open the Media Browser and navigate to the other project, after its loaded you have acces to all the assets.
Thanks Ann. I'm not sure I fully understand that. I would like to take a few
seconds of timeline from the middle of one project and transfer it to the
middle of another programme. I'm afraid I've been unable to find a way to do
this from MediaBrowser. Have I missed something?
From Media Browser, navigate to that older Premiere Pro project and click on it. You will then see all the assets in that project. Import the sequence in question into the new project. Load that into the Source Monitor, set your In/Out points, then add to the sequence as desired.
I'll try that.
